“…These results agree with those in [6], for concrete with incorporation of identical PET aggregates in the same substitution ratios. In [11,12], the authors relate the increase or decrease of shrinkage, to the lower and higher aggregates' modulus of elasticity, respectively.…”

“…Different types of plastic waste have been used as aggregate, filler or fibre in cement mortar and concrete after mechanical treatment. They include: polyethylene terephthalate (PET) bottles, polyvinyl chloride, PVC pipes, high density polyethylene, HDPE, thermosetting plastics, mixed plastic waste, expanded polystyrene foam, polyurethane foam, polycarbonate, and glass reinforced plastic [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21] . The details about the generation of PA as well as the properties of concrete containing PA are presented in a recent review 22 .…”

This paper reports the strength behaviour of concrete containing three types of recycled polyethylene terephthalate (PET) aggregate. Results are also analysed to determine the PET-aggregate's effect on the relationship between the flexural and splitting tensile strengths and compressive strength and to know whether the relationships between compressive strength and other strength characteristics given in European design codes are applicable to concrete made with PET-aggregates. The compressive strength development of concrete containing all types of PET-aggregate behaves like in conventional concrete, though the incorporation of any type of PET-aggregate significantly lowers the compressive strength of the resulting concrete. The PET-aggregate incorporation improves the toughness behaviour of the resulting concrete. This behaviour is dependent on PET-aggregate's shape and is maximised for concrete containing coarse, flaky PET-aggregate. The splitting tensile and flexural strength characteristics are proportional to the loss in compressive strength of concrete containing plastic aggregates.

“…Numerous academic researchers in theory and many concrete manufacturers in practice attach significant importance to recycling and reusing issues of the concrete waste. This kind of studies in the related literature have usually been directed to the use of the crushed concrete waste either as a road-base fill material or in place of the virgin or artificial aggregate for the new concrete and asphalt pavement (Herrador, Perez, Garach & Ordonez, 2012;Kou, Zhan & Poon, 2012;Silva, de Brito & Saikia, 2013). However, in order to sustain these recycling and reusing efforts in terms of commercial and environmental purposes, the potential amount of the concrete waste that can be produced in a batching plant and in Details of these researches are given in Table 1 below.…”

1280In the current study, how planning and truck-mixer based waste amounts per 1 m 3 fresh ready-mixed concrete (RMC) can be determined was presented. Toward this aim, the formation process of the fresh RMC waste in construction projects was first introduced in a detailed manner, together with an in-depth literature review in this specific domain of the construction engineering and management. Then, the measurement procedure of the waste amount or coefficient of the fresh RMC was revealed and discussed as a practical and creative planning knowledge. Hence, a useful and realistic waste management perspective about the cost and potential environmental savings of the RMC waste was drawn. Fresh Ready-Mixed Concrete Waste in Construction Projects IntroductionConstruction wastes not only affect the economy of a country, but also consume natural resources and pollute the environment for a very long term. According to Garvin (2004), 40-50% of the energy produced in the world and 16% of available water resources are consumed to produce construction materials defined as waste. CO2 that appears in the production process of such materials makes up 50% of the total CO2 emission in construction. Given the transportation of these material wastes, this share of 50% likely reaches up to 75%. In this environmental pollution and resource consumption, it should be noted that the cement manufacture plays an important role. In addition, construction wastes occupy large areas by volume. They have a share of approximately 20-40% of the total area occupied by wastes in the US, Canada, Hong Kong, Australia, Japan, and European Union countries (Stokoe, Kwong & Lau, 1999;Kibert, 2000;Poon, 2007). This share can likely increase further if wastes are measured in weight (Mulheron, 1988;Hendriks & Pietersen, 2000). Today, the construction industry tries to deal with enormous amounts of wastes as they are very damaging to the environment. However, it is very hard to assert that the construction industry has generally constituted and improved its waste-based business culture so far. In order to reveal the current position of the construction industry as a whole in terms of types and amounts of construction wastes, it is inevitable that various types of estimates and plans on sub-sectors of the construction industry should be carried out.In this context, how planning and truck-mixer based waste amounts per 1 m 3 fresh ready-mixed concrete (RMC) can be determined was presented in the current paper as a part of an on-going research project. This is because, in a reinforced-concrete building project, concrete can have a big share of about 10% of the total project budget (Kazaz, Ulubeyli & Turker, 2004). Of course, these amounts can be single numbers or interval-based values. This decision can be based on a statistical analysis of the real world data. Thus, while preparing their proposals, construction contractors in general and quantity surveyors and cost managers in particular can better estimate the amount and cost of RMC by means of these numeri...
